Valley of Fire State Park in Nevada covers 34,880 acres, dedicated in 1935, located 50 miles NE of Las Vegas. The rough floor and jagged walls of the park are brilliant formations of eroded red sandstone and sand dunes more than 150 million years old, which appear to be on fire when reflecting the sun's rays. Complex uplifting and faulting, followed by extensive erosion, created the present landscape. Other rock formations include limestones, shales, and conglomerates.
